You could possibly do this with a SRF; you'd have to grab the name of
the table and then build a dynamic query off of that. If you cast the
oid to regclass you'll get the name of the table, though you should
probably query pg_class and pg_namespace to build a fully-qualified
table name (schemaname.tablename).
